ABSTRACT:
A regulator circuit is provided that allows recovery in a controlled manner in the shortest possible time from occasional power line disturbances such as momentary line dropouts or under voltage. The voltage used to control switching of the switch mode converter follows the decrease in the output voltage during dropout, when switching of the switchmode converter ceases. When the line returns, the voltage used to control the switching is allowed to ramp up to the desired value providing a controlled recovery.
